Marie Curie, a Polish-born physicist and chemist who lived in France. She was a pioneer in the field of radioactivity, the first person awarded two Nobel Prizes, and the first female professor at the University of Paris. Her achievements include the creation of a theory of radioactivity (a term coined by her), techniques for isolating radioactive isotopes, and the discovery of two new elements, polonium and radium. It was also under her personal direction that the world's first studies were conducted into the treatment of neoplasms ("cancers"), using radioactive isotopes.
